APPARATUS FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 439,198, dated October 28, 1890.

Application filed May 22, 1890. Serial No. 352,810. (No model.)

To all whom it may concern.-

Be it known that I, HERMANN SoHULzE- BERGE, of Rochester, in the county of Beaver and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for the Manufacture of Glassware, of which the following is a full, clear, and exact description.

The present specification describes an improved apparatus for reheating and fire-melting glassware, which is illustrated in the accompanying sheets of drawings, in which- Figure 1 is a vertical section through the apparatus. Fig. 2 is a horizontal section on the line 11 II of Fig. 1. Fig. 3 on Sheet 2 is a similar horizontal section, showing a modified construction of the apparatus. FigsA to 9 are detail views hereinafter referred to.

Like symbols of reference indicate like parts in each.

The apparatus comprises a reheating-furnace or glory-hole, together with mechanical devices for presenting the glass object thereto. In Figs. 1 and 2 only a part of the reheating-furnace 1 is shown. It is provided with one or more projecting parts 1, in which is located the entrance 2 for the glass object 3, and the flue 4 for conducting the gases of combustion into the chimney.

The passage 2 for the introduction of the glass article is located so that a horizontal supporting rodmay be moved in its supporting-frame to enter the furnace, preferably, sidewise. This is a desirable feature of my invention,and although in the drawings Ihave shown the passage 2 extending into the gloryhole from below, it will be understood that it may be made to extend thereinto from above.

Another important feature of my invention, separately claimed herein, consists in arranging the supporting-rod in bearings carried by a swinging frame which is movable in the arc of a circle to introduce the supportingrod into the furnace, the supporting-rod being adapted to revolve laterally around the axis on which its bearings swings In the drawings the frame is shown as supported in a horizontal axis and arranged so that it shall swing downwardly from its extreme back position, in which the glass article is placed on the supportingrod,into its extreme forward position into the glory-hole.

It will be understood, however, that by mak--- ing the passage 2 to extend from the top of the furnace the sweep of the frame may be upwardly from its extreme back position, or that by making the passage 2 to enter the glory-hole from the side of the furnace the frame may be made to swing on a vertical axis. The advantage of mounting the sup porting-rod in a swinging frame is that the operator is removed from the intense heat at the neighborhood of the furnace, and the work is thereby rendered easier and more rapid.

A shaft or axle 7 is mounted in bearings 27 upon the two standards 7 in front of the proj ection 1', and is provided with arms 6 and 6',

adapted to oscillate or swing on the axis of the shaft 7. These arms are provided with brackets 8 and 8, so that each arm affords two bearings, in which are journaled supporting-rods 9 and 9', which are revoluble in the same axial line and are adapted to hold between them a glass object 3 to be reheated and finished. The supporting-rod 9' is longitudinally movable in its bearings by means .of the handle 10 actuating an angle-lever 11, 7

attached to a socket or collar 12 by means of links 13, in which collar the supporting-rod 9 is revoluble. This supporting-rod is forced toward the glass article by means of the angle-lever 11 and the contracting spring 14. From this construction it is evident that by pulling on the handle 10 the supporting-rod 9' will recede from the glass object, which then can be removed or exchanged by means of a suitable spoon-like instrument.

The supporting-rod 9', which enters the cavity of the glass object, may be provided with a mandrel capable of sliding thereon,'as explained in my pending patent applications, Serial Nos. 326,489 and 338,061, and while revolving motion may be imparted to the rod 9 directly this is not necessary, since it will revolve by frictional contact with the revolving object.

The supporting-rod 9 neednot be longitudinally movable in its bearings, but is held in its place with reference to the bearings by means of a collar 15 and sprocket-wheel 16, secured upon the supporting-rod by set-screws or otherwise.

vided with a head to center and support the glass article 3, and revolving motion is im- ICO This supporting-rod is proparted to it by means of the sprocket-wheel 16 and link-belt 17 from the sprocket-wheel 18, loosely revoluble around the shaft 7.

Directly connected with the sprocket-wheel 18 is the sprocket-wheel 19, which receives the revolving motion transferred upon the supporting-rod 9 from some prime motor by means of a link belt.

The axle 7 is provided oppositely to the arms 6 with a counter-weight 21, which is somewhat heavier than necessary merely to counterbalance the fixtures connected with the arms 6. The axle 7 is also provided with a pinion 22, into which meshes a rack 23, actuated by the hand-lever 24. By moving the rack 23 one way or the other the shaft 7 is moved, and the arms 6, with the supporting-rods, are swung around said shaft into the reheating-furnace or out of it, as indicated in Fig. 1. The advantage obtained by this construction over previous ones consists in the following points: By making the arms 6 of suitable lengthsay about three feetthe operator can remain at a distance of from six to seven feet without being exposed to the intense heat issuing from the furnace. It is almost impossible to stand such heat uninterruptedly for any length of time at acloser range. Furthermore, the construction described obviates the necessity for the removal of the reheated glass object from the reheating apparatus to a separate finishing apparatus, since the operator, with the usual tools or by specially-adapted tools, can finish the object, which, after reheating, revolves mechanically in front of him.

To further overcome the inconvenience of the intense heat issuing from the furnace, I may provide a water-cooled jacket 25 around the glory-hole in such a way that the operation in the glory-hole can be observed and that no obstacle is afforded to the introduction or withdrawal of the article to be reheated. The water-cooled jacket 25 is located some distance from the walls of the glory hole, so that the heat issuing from the furnace can pass up vertically between the furnace and the jacket. A spy-hole 26 is made in the jacket, and there should also be made slits or passage-ways through which the arms 6 canmove toward the glory-hole. The revoluble supporting-rods 9 and 9 may likewise be cooled by water or cold air, as described in United States Patent N 0. 418,235.

If the glass article does not require to be held between two supporting-rodsas, for instance, if the article is stuck upon a supporting-rod or held thereto by a snap or catches, or if it is as yet connected with a blowpipe-such supporting-rods orblow-pipe may be placed exchangeably in the bearings on the arms 6, and may be revolved by frietional contact with a revolving disk journaled upon the arms 6, and the object may be reheated and finished in the same way as described with reference to the tumblers 3. This is represented in the modification shown in Fig. 3. The glass object 3 is here stuck up upon the punty or post 9, which is provided with a friction-disk 30 and a collar 31, both secured rigidly to the punty.

The arm 6 and bracket Sare provided with semicircular and deep recesses or notches, Figs. 5 to 9, into which-the punty can be dropped and in which it can be rotated. By swinging the oscillable arm 6 so as to present the glass object to the action of heat in the glory-hole the punty would drop out of such notches. This is prevented by an automatic lock consisting of a weighted crescent 33, Fig. 8, which moves in a countersunk guide or way on the arm 6 and on the bracket 8, as shown in Figs. 6, 7, and 9, the weight causing it always to remain in a vertical position, whether the arm 6 be horizontal, inclined,-or vertical. If, then, the arm 6 be turned one hundred and eighty degrees, the crescent will form a part of the bearings in which the punty revolves, as shown in Fig. 9. The lock-opens automatically again if the arm 6 be swung back into its former position, so that after finishing the glass object the punty may be exchanged or replaced by another one.

To insure frictional contact of the disk 30 on the punty or blow-pipe and the frictiondisk 29, journaled in the arm 6, the bearing in which the disk 29 is journaled is made movable in the arm 6, as represented by Fig. 4, which shows the bearing of the disk 29 being forced toward the disk 30 by a yielding spring 32.

The apparatus represented in Fig. 3 permits the introduction of two objects to be reheated in the same glory-hole opening. It is more convenient, however, for the operator to heat or fire-melt one object while he is finishingor manipulating the other one.

The drawings represent one of the supporting-rods in the furnace and the other in a re tracted position out of the furnace.

The-supporting-rods are shown to be journaled in the arm 6 and bracket 8 about parallel to to the shaft 7, on which axis the arm 6 swings. It is, however, evident that a slight deviation from such parallel position will not impair the operativeness of the apparatus, even if an imagined prolongation of the supporting-rod should form an acute angle with a prolongation of the shaft 7.

The words substantially parallel used in the claims are intended to cover the longitudinal (as distinct from the transverse) position of the supporting-rod with relation to the shaft '7, around which it oscillates laterally, whether it be absolutely parallel or whether it deviates somewhat from the parallel.

The finishing-toolssuch as r0llersas shown by 28, Fig. 2, brought to bear against the revolving glass object or the mandrel, come into direct contact with the reheated glass object, and if such tools are made from metal they are preferably made from aluminium, or alloys rich in aluminium, because this metal does not chill the hot and plastic IIO glass as quickly or as strongly as if the tool is made from heavy metal, such as iron and copper. The finishing-tools of aluminium do not absorb so much heat from the hot and plastic object, and consequently the glass object, remaining plastic for a longer time, can more easily be reshaped than if heated with other metallic finishing-tools of the same size and shape.

I claim- 1. In apparatus for reheating or finishing glassware, the combination,with a glory-hole furnace, of a supporting rod journaled in swinging bearings whose path of motion extends to the glory-hole, said supporting-rod being substantially parallel to and adapted to revolve around the axis on which said bearings swing, substantially as and for the purposes described.
